Nations weapons types and quantities

So here i am thinking just what waepns do nations have in their inventory and how many. See we often here claims of various nations having a certain weapons systems such as A-A missiles but how many does each country actually own?

Is there a source that states what stocks of weaponry nations have or is it all pure guess work? What got me thinking was mainly how many AMRAAM’s the RAF have but from there I wondered how many Storm Shadows we have and so on (you get the idea)

I felt a google search would be pretty long winded taking hours and hours going through each nations weapons inventory so has anyone complied a list for the inquisitive like myself?
